SMF 1.1.x to phpBB3

Convertor errors question - SMF 1.1.x to phpBB3

Hi there. First of all let me say that I REALLY want to switch to phpbb. I have wanted to for quite a while now, but SMF is getting my goat to the extreme the last couple of days so the time for action is here. Anyway... I read up on the convertor for smf to phpbb and saw that it should work for SMF 2.0. My forum (http://www.theflipsideforum.com) is SMF 2.0.1, so I gave 'er a go. I got an error midway through the process. It looks like this:

I tried commenting out the lines of code functions_smf11.php at line 236, as mentioned by the second error from the top, and continued from there with the successful completion of the script, but I couldn't log in to the forum and the database was only 13 MB compared to the ~300MB of the SMF database.

Any ideas on how to proceed? If I can convert this database I can finally ditch SMF. Please help! Thanks very much.
